Giving 21 month old amoxicillin is like WW3.

Our son has had amoxicillin before but this time around has been literal hell. He had an ear infection so we had to start amoxicillin twice a day. It’s been traumatic and awful. We have to hold him down, inject it in side of his mouth and even then he ends up spitting some out even if we close his mouth. I’ve tried to mix it in food, won’t do it. i’ve tried to blow on his face or hold his nose for a second (all ped recs) and nope. not only that but now giving him anything else is also a fight. My daughter loved amoxicillin and just never fought us. Has anyone else had this? Any tips or tricks that worked? I feel by the end of the 10 days we will all need trauma therapy.
